On Friday, Jan. 6, we learned about a bug that impacted our SSL certification validation process. The bug was introduced on July 29, 2016, and impacted less than 2 percent of the certificates issued from July 29, 2016, to Jan. 10, 2017. It affected approximately 6,100 customers. The software bug that created the issue has been remedied. We continue to closely monitor the system. We will revoke these certificates at 9 p.m. (PST) Jan. 10, 2017. We are actively working with our customers to reissue their SSL certificates.
